ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent NO. 338,856, dated March 30, 1886.

(No model.)

To all whom it may concern Be it known that we, MIoHAEL MoANENY and WILLIAM L. RIELEY, both citizens of the United States, and residents of Denver, in the 5 county of Arapahoe and State of Colorado, have invented a new and useful Improvement in Ore-Concentrators, of which the following is a specification, reference being had therein to the accompanying drawings, in which simi- I lar letters refer to corresponding parts.

Our invention relates to improvements in ore-concentrators, and the object of our improvements is toprovide a machine for separating the precious metals from the crude sub- I stance with which they are found mingled in gold or silver ore, said ore having been first passed through a stamp-mill and pulverized.

In the drawings, Figure 1 is a side elevation of our improved machine. Fig. 2 is a top view of the concentrating-box, showingapart of the motor-rod and spiral spring attached thereto. Fig. 3 is a transverse section of the concentrating-box, taken on the line y y, Fig.

2 Fig. 4 is a longitudinal section of the concentrating-box, taken on the line or m, Fig. 2.

Fig. 5 is a front elevation of the propelling mechanism. Fig. 6 is a top view of the machine after removing the concentrating-box 1 and its supporting-carriage and detaching the propelling mechanism. Fig. 7 is an elevated transverse section taken on the line 2 2, Fig. 1. Fig. Sis a side elevation of a portion of the concentrating-box, showing the bumper and platform upon which it rests.

In the drawings, a is a concentrating-box, in the bottom of which is placed the riflled plate a (distinctly shown in Fig. 4.) The material to be treated, together with the necessary quantity of water, is discharged into box a. Concentratingbox a rests upon the springbeams b b, said beams being supported by the rollers 0. Rollers 0 rest upon track cl, and are further supported, as shown in Figs. 1 and 7.

Rollers c are provided with flanges c, as usual, 4 5 to compel them to keep the track. To the bottom of concentratingbox a is attached the bumper a.

f is a platform constructed of any suitable suspended from abovein any suitable manner.

In the latter case the bumpers must be fashioned as shown in Fig. 8 in order to accomplish the desired result.

9 is a pulley attached to shaft h, which shaft works within journal boxes h. crank z is rigidly attached to the inner end of shaft h and turns with it. Crank t is attached to pin j, which passes through slot in lever k. The lower extremity of lever 7c is attached to socket Z by pin Z, which forms its fulcrum. 70

Through the upper part of lever 7c passes one extremity of the rod m. The opening k" in lever 70, through which rod m passes, is somewhat longer than the diameter of the rod, as

shown in Fig. 5. Opening It allows rod on a slight vertical movement, as shown by dotted lines in Fig. 1. The other extremity of rod m is attached to a hanger, a, upon the bottom of concentrating-box a. Rod on has a longitudinal movement within lever 70, but is sta- 0 tionary within hanger a". Between hanger a and lever is is the spiral spring a, which is supported and held in position by rod m, which passes through said spring.

Our improved machine may be operated by any suitable motor, power being applied by attaching a belt to pulley g, which sets shafts h in motion. The movement of shaft h imparts motion to lever is by means of crank 2. As crank t' revolves with shaft h pin j is caused 96 to move in slot It, thus communicating an oscillatory movement to lever is. The movement of lever 70 gives motion to concentrating-box a by means of rod or and spring a. As concentrating-box a moves forward upon rollers 0 bumper a is brought suddenly in The 65 contact with bumper f. By reason of the obliquity of the contact-surfaces ofthe bumpers, as shown in Fig. 1, concentrating-box a is raised slightly at the instant the bumpers come in contact, thus giving said boxa vibratory movement caused by the vibration of the spring-beams b, upon which box a rests.

The use of spring-beams b and bumpers a andf may be more fully explained as follows:

The contact-surfaces of the bumpers being ob-- lique, and the obliquity being as shown in Fig. 1, the contact-surface of bumper a moves upward slightly upon the inclined plane formed by the contact surface of bumper f. The greater the degree of obliquity of the contactsurfaces of these bumpers the greater the facility of this upward movement of bumper a upon bumper f. The degree of obliquity of the contact-surfaces of these bumpers may be as great as may be desired, in order to accomplish the result sought. The upward movement of bumper a just described raises concentrating-box a, thus causing the springbeams b to bend upward between their extremities, which remain stationary, the contact of the bumpers being so sudden that the resistance caused by the weight of the rollers attached to the extremities of the spring-beams is not overcome. After the contact ,of the bumpers a and f, with the result just explained, the beams b spring to their original position, thus giving the vibratory movement to box, as before mentioned. The springbeams should be so constructed as to facilitate this springing movement, caused by the sudden and forcible contact of the oblique surfaces of the bumpers a and f, as aforesaid.

When concentrating-box a is supported from above as before referred to, the supporting rods must be attached to spring-beams b at or near the extremities of said beams, andthen the bumpers used must be fashioned as shown inFig. 8, or, in other words, the obliquity of the bumpers shown in Fig. 1 must be reversed, thus causing the contact-surface of bumper a to move downward upon the inclined plane formed by bumper f, thus giving a downward movement to concentratingbox a, and causing spring-beams b to bend downward between their extremities, said extremities being held in position and given the requisite resistance by the supporting-rods attached as aforesaid. When concentrating-box a is suspended from above and the bumpers are fashioned as shown in Fig. 8, the sudden contact of the bumpers causes a slight downward movement, which also gives box a a vibratory movement. The sudden contact of crude material.

the bumpers causes box a with its carriagesupport to spring back, forcing rod m through lever is, and causing its extremity to project beyond said lever, as shown in the drawings, thus contracting spiral spring n. Spring n being contracted by the rebound just'described, immediately forces box a with its support forward, bringing the bumpers in contact again, by means of which motion the material in box a is separated into two partsnamely, the valuable and worthless. The vibration of box a keeps the material in said box continually in motion, causing the precious metal to settle to the bottom, it being heavier than the Under the influence of the sudden jar caused by the contact of the bumpers the precious metal, resting upon the bottom of box a and within the riffles, is carried forward upon riffled plate a and is discharged through the opening 0 into any suitable receptacle. The jar causes by the sudden contact of the bumpers caused a backward wave in the water contained in box a, which wave carries the light and crude material with it, washing the same over the elevated riffle a, when it is discharged from the machine through the openings 0 0. (Shown in Figs. 1 and 7.)

What we claim as our invention, and desire to secure by Letters Patent, is

1. In an oreconcentrator, the combination of concentrating-box a, provided with riflled plate a bumper a, hanger a, and a movable support, bumper f, platform f, and mechanism for propelling concentrating-box a, -consisting of shank h, crank z, pin j, lever k, provided with'slots k and k, and a suitable fulcrum, rod m, and spring n, substantially as described and shown, and for the purpose set forth.

2. In an ore-concentrator, the combination of concentrating-box a, provided with 'rifiled plate a and oblique bumper a, a supportingcarriage for concentrating-box (1, consisting of spring-beams b and rollers c, oblique bumper f, platform f, and suitable mechanism for propelling concentrating-box a.

3. In an ore-concentrator, the combination of a concentrating-box provided with oblique bumper a, spring-beams b, provided with a suitable support, and oblique bumper f, provided with a suitable supporting-platform, substantially as described, and for the purpose set forth.
